Directed by James Mangold. With Hugh Jackman, Patrick Stewart, Dafne Keen, Boyd Holbrook. In the near future, a weary Logan cares for an ailing Professor X, somewhere on the Mexican border. However, Logan's attempts to hide from the world, and his...

Yeah these guys are just delightful weirdos for the most part. So on the ball bearing I just figured it was a clever joke and practical effect. But the claws part clearly involved some CG. So its likely clever marketing.

I suspect this may have been an adamantium/vibranium alloy. Normally when he puts very hard substances under the press, his table shifts and buckles a bit, but that was not visible here, presumably because the vibranium was absorbing the kinetic energy.

I’m impressed at how close to his natural “voice” they kept everything. This is exactly how it would go in a world where Wolverine existed and got hooked up with a Finnish YouTube channel about industrial presses.

Best case the electric field of the molecules push against each other like normal matter, leaving the slightly unequal force of the repulsion against Earth’s gravitational field to force it to press one-gee harder on the top plate, but the equal and not-opposite pressures on the two plates mostly cancel out and the negative matter is crushed like normal matter.

But worst case the negative matter mutually erases itself and an equal mass of the press plate’s molecules on contact, suddenly changing the masses of countless subatomic particles and releasing a hail of deconfined quarks that would destroy the Earth!
